    Oops!! I missed a part of the problem
    during my 1st response.

    (-1.2X^6 -0.018X^5 +4.2X^2) / -6X^4
    Divide each term by -6X^4:
    2X^2 0.003X -0.7/X^2.
    Remember to subtract the exponents when dividing.
    The last term of the answer had a
    negative exponent. So it was moved to the
    denominator as a positive exponent

    (18Y^3 -5Y^12 -7Y^11)/(3/2)Y.
    Arrange exponents in decreasing order:
    -5Y^12 - 7Y^






    (-1.2X^6 - 0.018X^5 +4.2X^2)/-6X^4
    Divide each term by -6X^4:
    2X^2 + 0.003X - 0.7/X^2

    (18Y^3 - 5Y^12 - 7Y^11)/(3/2)Y.
    Arrange exponents in decreasing order:
    (-5y^12 - 7y^11 + 18y^3)/(3/2)Y
    Divide each term by y:
    (-5Y^11 -7Y^10 + 18Y^2)/(3/2).
    Multiply denominator and numerator
    by 2/3:
    2/3(-5Y^11 -7Y^^10 + 18Y^2.
    Factor out Y^2:
    (2/3)Y^2(-5Y^9 -7Y^8 + 18)
